An Unusual Cat

Willow was a girl under the protection of the Autobots. Ratchet was her guardian, and surprised everyone at base when he willingly accepted. Willow has been with the Autobots for a few weeks, staying out of trouble unlike the other kids.
She never had a pet before and it was quite lonely when she always came back home. She wanted a friend that would greet her, and curl in her lap when she took a nap.
Her parents never liked pets, and when Willow wanted a cat they were livid. After much negotiation, her parents promised to get her a cat for her next birthday.
What happens when she is gifted with the largest silver Maine Coon cat, that had unnatural red eyes?
